Element M is a shiny and highly reactive metal (melting point 63°C), and element X is a highly reactive nonmetal (melting point −7.2°C). They react to form a compound with the empirical formula MX, a colorless, brittle white solid that melts at 734°C. When dissolved in water or when in the molten state, the substance conducts electricity. When chlorine gas is bubbled through an aqueous solution containing MX, a reddish-brown liquid appears and Cl − ions are formed. From these observations, identify M and X. (You may need to consult a handbook of chemistry for the melting-point values.)

Which will evaporate faster, 1-Butanol or Pentane? Explain your choice.
Using the equation below, what is the rate of this reaction if the rate of disappearance of H2 is 0.44 M/sec?
H2 + Br2 → 2HBr
2Fe3+(aq) + Sn2+(aq) □ 2Fe²+(aq) + Sn 4+ (aq)
If the change in Sn²+ concentration is 0.0010M in 38.5 seconds, what is the rate of disappearance of
Sn²+?
